If you do want Elastic Transcoder to create thumbnails, specify the information that
you want to include in the file name for each thumbnail. You can specify
the following values in any sequence:

CopyC#

{count}

(Required): If you want to create
thumbnails, you must include

CopyC#

{count}

in the

CopyC#

ThumbnailPattern

object. Wherever you specify

CopyC#

{count}

, Elastic Transcoder
adds a five-digit sequence number (beginning with 00001)
to thumbnail file names. The number indicates where a given thumbnail
appears in the sequence of thumbnails for a transcoded file.

If you specify a literal value and/or

CopyC#

{resolution}

but you omit

CopyC#

{count}

, Elastic Transcoder returns a
validation error and does not create the job.

Literal values (Optional): You can specify literal values
anywhere in the

CopyC#

ThumbnailPattern

object. For example,
you can include them as a file name prefix or as a delimiter between

CopyC#

{resolution}

and

CopyC#

{count}

.

CopyC#

{resolution}

(Optional): If you want Elastic
Transcoder to include the resolution in the file name, include

CopyC#

{resolution}

in the

CopyC#

ThumbnailPattern

object.

When creating thumbnails, Elastic Transcoder automatically saves the files in the
format (.jpg or .png) that appears in the preset that you specified in
the
